RESUMEN

BACKGROUND: Increased consumption of ultra-processed foods (UPFs) which have additives such as artificial colours, flavours and are usually high in salt, sugar, fats and specific preservatives, are associated with diet-related non-communicable diseases (NCDs). In India, there are no standard criteria for identifying UPFs using a classification system based on extent and purpose of industrial processing. Scientific literature on dietary intake of foods among Indian consumers classifies foods as unhealthy based on presence of excessive amounts of specific nutrients which makes it difficult to distinguish UPFs from other commercially available processed foods. METHODS: A literature review followed by an online grocery retailer scan for food label reading was conducted to map the types of UPFs in Indian food market and scrutinize their ingredient list for the presence of ultra-processed ingredients. All UPFs identified were randomly listed and then grouped into categories, followed by saliency analysis to understand preferred UPFs by consumers. Indian UPF categories were then finalized to inform a UPF screener. RESULTS: A lack of application of a uniform definition for UPFs in India was observed; hence descriptors such as junk-foods, fast-foods, ready-to-eat foods, instant-foods, processed-foods, packaged-foods, high-fat-sugar-and-salt foods were used for denoting UPFs. After initial scanning of such foods reported in literature based on standard definition of UPFs, an online grocery retailer scan of food labels for 375 brands (atleast 3 brands for each food item) confirmed 81 food items as UPFs. A range of packaged traditional recipes were also found to have UPF ingredients. Twenty three categories of UPFs were then developed and subjected to saliency analysis. Breads, chips and sugar-sweetened beverages (e.g. sodas and cold-drinks) were the most preferred UPFs while frozen ready-to-eat/cook foods (e.g. chicken nuggets and frozen kebabs) were least preferred. CONCLUSION: India needs to systematically apply a food classification system and define Indian food categories based on the level of industrial processing. Mapping of UPFs is the first step towards development of a quick screener that would generate UPF consumption data to inform clear policy guidelines and regulations around UPFs and address their impact on NCDs.

RESUMEN

Cultured meat is a promising substitute for regular meat, but its introduction faces challenges and expected consumer resistance. While some studies investigate how communication strategies and advertising appeals can address these concerns, the role of social media influencers in promoting cultured meat adoption remains yet to be explored. Across two online experimental studies involving 752 participants recruited from Prolific, this research investigates how influencer type (micro- vs. mega-influencer) affects consumers' willingness to buy cultured meat. Study 1 reveals that consumers are more willing to buy cultured meat when it is endorsed by micro- rather than mega-influencers. Further, perceived endorsement authenticity mediates this effect such that micro-influencers endorsements are perceived as more authentic than those of mega-influencers. Study 2 demonstrates that these effects are moderated by influencer expertise and type of meat, where micro-influencers with health (but not fashion) expertise have a more pronounced impact on increasing willingness to purchase cultured meat (but not regular meat). This research provides theoretical insights into how consumers perceive influencer endorsements for cultured meat. These findings aim to enhance consumer acceptance of cultured meat while offering actionable guidance for practitioners on promoting cultured meat brands on social media.

RESUMEN

Fungicides are often used prophylactically, to control fungal diseases. Although fungicides have been designed to control pests/fungi, they frequently share molecular targets with non-target species, including humans. Tebuconazole, a fungicide belonging to the class of triazoles, is widely employed, has moderate to high persistence in soil, and can be found in different environmental levels. This fungicide is metabolized to the main hydroxy-derived metabolite, Tebuconazole-tert-butyl-hydroxy (or hydroxytebuconazole). This study aims to unveil the action mechanism of Tebuconazole and the role played by its metabolite, Tebuconazole-tert-butyl-hydroxy (5-(4-Chlorophenyl)-2,2-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)-1,3-pentanediol), within the expected spectrum of toxicity. In silico and in vitro analyses (MTT assay, cell cycle evaluation, annexin/PI assay, ROS accumulation assay, and mitochondrial membrane potential determination) were performed in HepG2 cells for 24 h and 48 h. Although in silico analysis suggested that both Tebuconazole and Tebuconazole-tert-butyl-hydroxy are potentially hepatotoxic, only Tebuconazole affected the tested cell line. Reduced MTT metabolism, and decreased mitochondrial membrane potential were the main findings. In conclusion, the action mechanism of Tebuconazole may be related to mitochondrial dysfunction. However, the findings of this study pointed out that Tebuconazole-tert-butyl-hydroxy does not play an important role in Tebuconazol toxicity. The study has generated new data that will help to understand how fungicides behave in the environment.

RESUMEN

Fungicides are specifically used for controlling fungal infections. Strobilurins, a class of fungicides originating from the mushroom Strobilurus tenacellus, act on the fungal mitochondrial respiratory chain, interrupting the ATP cycle and causing oxidative stress. Although strobilurins are little soluble in water, they have been detected in water samples (such as rainwater and drinking water), indoor dust, and sediments, and they can bioaccumulate in aquatic organisms. Strobilurins are usually absorbed orally and are mainly eliminated via the bile/fecal route and urine, but information about their metabolites is lacking. Strobilurins have low mammalian toxicity; however, they exert severe toxic effects on aquatic organisms. Mitochondrial dysfunction and oxidative stress are the main mechanisms related to the genotoxic damage elicited by toxic compounds, such as strobilurins. These mechanisms alter genes and cause other dysfunctions, including hormonal, cardiac, neurological, and immunological impairment. Despite limitations, we have been able to compile literature information about strobilurins. Many studies have dealt with their toxic effects, but further investigations are needed to clarify their cellular and underlying mechanisms, which will help to find ways to minimize the harmful effects of these compounds.

RESUMEN

BACKGROUND: Ultra-processed foods (UPF), as proposed by the Nova food classification system, are linked to the development of obesity and several non-communicable chronic diseases and deaths from all causes. The Nova-UPF screener developed in Brazil is a simple and quick tool to assess and monitor the consumption of these food products. The aim of this study was to adapt and validate, against the 24-hour dietary recall, this short food-based screener to assess UPF consumption in the Senegalese context. METHODS: The tool adaptation was undertaken using DELPHI methodology with national experts and data from a food market survey. Following the adaptation, sub-categories were renamed, restructured and new ones introduced. The validation study was conducted in the urban area of Dakar in a convenience sample of 301 adults, using as a reference the dietary share of UPF on the day prior to the survey, expressed as a percentage of total energy intake obtained via 24-hour recall. Association between the Nova-UPF score and the dietary share of UPF was evaluated using linear regression models. The Pabak index was used to assess the agreement in participants' classification according to quintiles of Nova-UPF score and quintiles of the dietary share of UPF. RESULTS: The results show a linear and positive association (p-value < 0.001) between intervals of the Nova-UPF score and the average dietary share of UPF. There was a near perfect agreement in the distribution of individuals according to score's quintiles and UPF dietary share quintiles (Pabak index = 0.84). CONCLUSION: The study concluded that the score provided by the Nova-UPF screener adapted to the Senegalese context is a valid estimate of UPF consumption.

RESUMEN

OBJECTIVE: To report the need for cord untethering after prenatal repair of open spina bifida using a unique biocellulose-based technique performed at a later gestational age. METHODS: An observational cohort study was conducted to determine the incidence of tethered cord syndrome. Between May 2013 and May 2022, we performed 172 procedures using the percutaneous fetoscopic approach in fetuses at 26-28 weeks of gestation. After placode dissection, a biocellulose patch was placed to cover the placode, a myofascial flap (when possible) was dissected, and the skin was closed. Owing to death or loss to follow-up, 23 cases were excluded. Cord tethering syndrome was defined as symptoms of medullary stretching, and the infants were evaluated and operated on by local neurosurgeons after an magnetic resonance imaging examination. Infants over 30-month had ambulation and neurodevelopment evaluations (PEDI scale). RESULTS: Among 172 cases operated at a median gestational age of 26.7 weeks and delivered at 33.2 weeks, 149 cases were available for postnatal follow-up, and cord untethering was needed in 4.4% of cases (6/136; excluding 13 cases younger than 12 months). Cerebrospinal fluid diversion and bladder catheterization were needed in 38% and 36% of cases, respectively. Of the 78 cases evaluated at 30 months, 49% were ambulating independently, and 94% had normal social function. CONCLUSION: The biocellulose-based technique was associated with a low rate of cord tethering, wich may be attributed to the lack of the duramater suture during prenatal repair, the formation of a neoduramater and/or later gestational age of surgery.

RESUMEN

Ensuring the sustainability and circularity of mixed crop-ruminant livestock systems is essential if they are to deliver on the enhancement of long-term productivity and profitability with a smaller footprint. The objectives of this study were to select indicators in the environmental, economic and social dimensions of sustainability of crop-livestock systems, to assess if these indicators are relevant in the operational schedule of farmers, and to score the indicators in these farm systems. The scoring system was based on relevance to farmers, data availability, frequency of use, and policy. The study was successful in the assemblage of a suite of indicators comprising three dimensions of sustainability and the development of criteria to assess the usefulness of these indicators in crop-ruminant livestock systems in distinct agro-climatic regions across the globe. Except for ammonia emissions, indicators within the Emissions to air theme obtained high scores, as expected from mixed crop-ruminant systems in countries transitioning towards low emission production systems. Despite the inherent association between nutrient losses and water quality, the sum of scores was numerically greater for the former, attributed to a mix of economic and policy incentives. The sum of indicator scores within the Profitability theme (farm net income, expenditure and revenue) received the highest scores in the economic dimension. The Workforce theme (diversity, education, succession) stood out within the social dimension, reflecting the need for an engaged labor force that requires knowledge and skills in both crop and livestock husbandry. The development of surveys with farmers/stakeholders to assess the relevance of farm-scale indicators and tools is important to support direct actions and policies in support of sustainable mixed crop-ruminant livestock farm systems.

RESUMEN

Abstract Background The most frequent cause of death in neurosurgical patients is due to the increase in intracranial pressure (ICP); consequently, adequate monitoring of this parameter is extremely important. Objectives In this study, we aimed to analyze the accuracy of noninvasive measurement methods for intracranial hypertension (IH) in patients with traumatic brain injury (TBI). Methods The data were obtained from the PubMed database, using the following terms: intracranial pressure, noninvasive, monitoring, assessment, and measurement. The selected articles date from 1980 to 2021, all of which were observational studies or clinical trials, in English and specifying ICP measurement in TBI. At the end of the selection, 21 articles were included in this review. Results The optic nerve sheath diameter (ONSD), pupillometry, transcranial doppler (TCD), multimodal combination, brain compliance using ICP waveform (ICPW), HeadSense, and Visual flash evoked pressure (FVEP) were analyzed. Pupillometry was not found to correlate with ICP, while HeadSense monitor and the FVEP method appear to have good correlation, but sensitivity and specificity data are not available. The ONSD and TCD methods showed good-to-moderate accuracy on invasive ICP values and potential to detect IH in most studies. Furthermore, multimodal combination may reduce the error possibility related to each technique. Finally, ICPW showed good accuracy to ICP values, but this analysis included TBI and non-TBI patients in the same sample. Conclusions Noninvasive ICP monitoring methods may be used in the near future to guide TBI patients' management.


Resumo Antecedentes A causa mais frequente de morte em pacientes neurocirúrgicos é devido ao aumento da pressão intracraniana (PIC); consequentemente, o monitoramento adequado desse parâmetro é de extrema importância. Objetivos Avaliar na literatura científica os principais métodos não invasivos de medida da PIC em pacientes com traumatismo cranioencefálico (TCE). Métodos Os dados foram obtidos na base de dados PubMed, utilizando os seguintes termos: pressão intracraniana, não invasivo, monitoramento, avaliação e medida, resultando em 147 artigos. Os artigos selecionados datam de 1980 a 2021, sendo todos estudos observacionais ou ensaios clínicos, em inglês e especificando a medida da pressão intracraniana em traumatismo cranioencefálico. Ao final da seleção, 21 artigos foram incluídos nesta revisão. Resultados Foram analisados os seguintes métodos: diâmetro da bainha do nervo óptico (ONSD), pupilometria, doppler transcraniano (TCD), combinação multimodal, complacência cerebral por meio da análise de ondas intracerebrais (ICPW), HeadSense e visual evocado por flashes de luz (FVEP). A pupilometria não se correlacionou com os valores de PIC, enquanto que o monitor HeadSense e o método FVEP parecem ter uma boa correlação, mas os dados de sensibilidade e especificidade desses métodos não estão disponíveis. Os métodos ONSD e TCD mostraram acurácia de boa a moderada quanto aos valores de IPCi, além de bom potencial para detectar hipertensão intracraniana. Ademais, a combinação multimodal pode reduzir a possibilidade de erro relacionado a cada técnica. Por fim, o ICPW apresentou boa acurácia quanto aos valores de ICPi, mas, no estudo analisado, foram incluídos pacientes com e sem TCE em uma mesma amostra. Conclusões Métodos não invasivos de medição da PIC podem atuar no futuro no manejo de pacientes com TCE como uma potencial ferramenta de triagem para TCE grave e para a detecção de hipertensão intracraniana.

RESUMEN

Resumo O objetivo deste artigo é caracterizar os apelos publicitários presentes no ambiente alimentar para comercializar alimentos ultraprocessados e analisar o perfil nutricional desses alimentos segundo critérios da OPAS e presença de aditivos alimentares. Estudo transversal, com dados auditados em 20 pequenos supermercados de São Paulo. O protocolo INFORMAS foi utilizado para classificar as mensagens publicitárias. Os alimentos foram classificados segundo a NOVA. O perfil nutricional da OPAS foi utilizado para classificar os alimentos elevados em nutrientes críticos. Os padrões de publicidade foram identificados por análise fatorial. A associação entre os padrões e os grupos de alimentos foi investigada por regressão linear. Mais de 95% dos alimentos ultraprocessados tinham pelo menos um nutriente crítico em excesso. Verificou-se associação positiva entre o padrão nova marca, divertido e vantajoso com salgadinhos, produtos pré-prontos, lácteos e biscoitos, e entre o padrão nova marca e uso sugerido com lácteos. A padronização da publicidade de alimentos nos pequenos comércios varejistas está associada à oferta de salgadinhos, produtos lácteos, alimentos pré-prontos e biscoitos, produtos que excedem em nutrientes críticos.


Abstract This article aims to characterize the advertising appeals present in the food environment to market ultra-processed foods and to analyze the nutritional profile of these foods according to PAHO criteria and the presence of food additives. Cross-sectional study, with data audited in 20 small supermarkets in São Paulo. The INFORMAS protocol was used to classify the advertising messages. The foods were classified according to NOVA. The PAHO profile model was used to classify foods high in critical nutrients. Advertising patterns were identified by factor analysis. The association between patterns and food groups was investigated by linear regression. More than 95% of the ultraprocessed foods had at least 1 critical nutrient in excess. There was a positive association between the new brand, fun and advantageous pattern with snacks, ready-made products, dairy products and cookies; between the new brand and suggested use pattern with dairy products. The standardization of food advertising in small retail stores is associated with offering snacks, dairy products, ready-to-eat foods and cookies, products that exceed critical nutrients.

RESUMEN

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.


Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

RESUMEN

ABSTRACT OBJECTIVE To study the association between ultra-processed food consumption and carbon and water footprints of the Brazilian diet. METHODS Cross-sectional analysis on data collected in 2008-2009 on a probabilistic sample of the Brazilian population aged ≥ 10 years (n = 32,886). Individual food intake was assessed using two 24-hour food records, on non-consecutive days. The environmental impact of individual diets was calculated by multiplying the amount of each food by coefficients that quantify the atmospheric emissions of greenhouse gases in grams of carbon dioxide equivalent (carbon footprint) and freshwater use in liters (water footprint), both per gram or milliliter of food. The two coefficients consider the food life cycle 'from farm to fork.' Crude and adjusted linear regression models and tests for linear trends assessed the association between the ultra-processed food contribution to total energy intake (quintiles) and the diet carbon and water footprints. Potential confounders included age, sex, education, income, and region. Total energy intake was assessed as a potential mediation variable. RESULTS In the crude models, the dietary contribution of ultra-processed foods was linearly associated with the carbon and water footprints of the Brazilian diet. After adjustment for potential confounders, the association remained significant only regarding the diet water footprint, which increased by 10.1% between the lowest and highest quintile of the contribution of ultra-processed foods. Additional adjustment for total energy intake eliminated this association indicating that the dietary contribution of ultra-processed foods increases the diet water footprint by increasing energy intake. CONCLUSIONS The negative impact of ultra-processed foods on the diet water footprint, shown for the first time in this study, adds to the negative impacts of these foods, already demonstrated regarding dietary nutrient profiles and the risk for several chronic non-communicable diseases. This reinforces the recommendation to avoid ultra-processed foods made in the official Brazilian Dietary Guidelines and increasingly in dietary guidelines of other countries.

RESUMEN

ABSTRACT OBJECTIVE To estimate beef consumption and its influence on carbon and water footprints, as well as to improve the nutritional quality of the Brazilian diet. METHODS The amount of beef and other foods consumed was evaluated by two 24-hour food records in a representative sample of the Brazilian population ≥ 10 years of age (n = 32,853) from 2008 to 2009. The environmental impact of the diet considered the coefficients of the carbon footprint (gCO2 and/kg) and the water footprint (liters/kg) of the foods, as well as their nutritional quality considering the nutrient composition of each food associated with the prevention of nutritional deficiencies or the increase/decrease in chronic disease risk. Linear and logistic regression models, crude and adjusted for sex, age, education, income, region, and area, were used to respectively study the association of fifths of the caloric contribution of beef with the environmental impacts of the diet and inadequate nutrient intake. RESULTS Carbon and water footprints and protein, iron, zinc, vitamin B12, saturated fat, and sodium contents were higher in the fraction of the diet composed of beef, whereas fiber and added sugar contents were higher in the fraction composed by the other foods. Dietary beef contribution was directly associated with the carbon and water footprints of the diet and the risk of saturated fat and sodium excess, besides fiber insufficiency, inversely associated with the risk of protein, iron, zinc, and vitamin B12 insufficiency. CONCLUSION Reducing beef consumption in Brazil would also reduce the carbon and water footprints of the diet, as well as the risk of chronic diseases related to food. Therefore, in order not to increase the risk of nutritional deficiencies, monitoring the increased intake of other foods rich in protein, iron, zinc, and vitamin B12 is suggested.


RESUMO OBJETIVO Estimar o consumo de carne bovina e a sua influência nas pegadas de carbono e na pegada hídrica, bem como mesurar a qualidade nutricional da dieta no Brasil. MÉTODOS A quantidade consumida de carne bovina e dos demais alimentos foi avaliada por dois registros alimentares de 24 horas em amostra representativa da população brasileira ≥ 10 anos de idade (n = 32.853) entre 2008 e 2009. O impacto ambiental da dieta considerou os coeficientes da pegada de carbono (gCO2e/kg) e da pegada hídrica (litros/kg) dos alimentos, bem como sua qualidade nutricional considerando a composição de cada alimento em nutrientes associados à prevenção de deficiências nutricionais ou ao aumento/diminuição do risco de doenças crônicas. Modelos de regressão linear e logística, brutos e ajustados para sexo, idade, escolaridade, renda, região e área, foram utilizados para estudar, respectivamente, a associação de quintos da contribuição calórica de carne bovina com os impactos ambientais da dieta e com a ingestão inadequada de nutrientes. RESULTADOS As pegadas de carbono e hídrica e os teores de proteína, ferro, zinco, vitamina B12, gordura saturada e sódio foram maiores na fração da dieta composta por carnes bovinas, enquanto o teor de fibra e de açúcar de adição foram maiores na fração composta pelos demais alimentos. A contribuição dietética de carne bovina mostrou-se associada diretamente com as pegadas de carbono e hídrica da dieta e com o risco de ingestão excessiva de gordura saturada e de sódio, além de ingestão insuficiente de fibra, associando-se inversamente com o risco de ingestão insuficiente de proteína, ferro, zinco e vitamina B12. CONCLUSÃO A redução no consumo de carne bovina no Brasil diminuiria as pegadas de carbono e hídrica da dieta, assim como o risco de doenças crônicas relacionadas à alimentação. Portanto, para não aumentar o risco de deficiências nutricionais, é sugerido o acompanhamento do aumento da ingestão de outros alimentos fontes de proteína, ferro, zinco e vitamina B12.

The purpose of this article is to report a practical experience in School Psychology at a public school in the city of João Pessoa. It is anchored in the assumptions of Vigotski's Historical-Cultural approach, considering the psychologist as a mediator of relationships and knowledge. In a perspective of preventive and institutional action, the intervention was carried out by Psychology professionals together with teachers, tutors, and school teachers, and the focus was sex education, aiming to give them other possibilities on the theme in order to enable an adequate approach to the demands of the students. Experience has shown that training with school professionals has the potential to promote new reflections and possibilities for action in the classroom. In addition, it corroborated the perspective of the role of the psychology professional as a mediator of reflections, training processes, and changes in methodologies, even though there are obstacles and difficulties in this process.

RESUMEN

ABSTRACT OBJECTIVE: To estimate the carbon footprint of the Brazilian diet and of sociodemographic strata of this population. METHODS: Carbon footprint of the diet was estimated based on data from two 24-hour diet records, obtained in 2008 and 2009, from a probabilistic sample of the Brazilian population aged 10 years and over (n = 34,003) and on environmental impact coefficients of food and culinary preparations consumed in Brazil (gCO2e/kg). Means with 95% confidence intervals of food consumption (kcal/person/day) and the carbon footprint of the diet (gCO2e/person/day and in gCO2e/2,000kcal) were calculated for the population as a whole and for strata according to sex, age, income, education, macro-regions and Federative Unit. Linear regression models were used to identify significant differences (p < 0.05) in the dietary carbon footprint of different sociodemographic strata. RESULTS: The average carbon footprint of the Brazilian diet was 4,489gCO2e/person/day. It was higher for males, for the age group from 20 to 49 years and for the North and Midwest regions, and tended to increase with income and education. The pattern of association of footprint with sociodemographic variables did not change substantially with adjustment for differences in the amount of food consumed, except for a reduction in the relative excess of the footprint among males and an increase in the relative excess of the footprint in the Midwest region. CONCLUSION: The carbon footprint of the Brazilian diet exceeds by about 30% the footprint of the human diet, which could simultaneously meet the nutritional requirements of a healthy diet and the global goal of containing the increase in the planet's average temperature. The pattern of association of this footprint with sociodemographic variables can help identify priority targets for public actions aimed at reducing the environmental impacts of food consumption in Brazil.


RESUMO OBJETIVO: Estimar a pegada de carbono da dieta brasileira e de estratos sociodemográficos dessa população. MÉTODOS: A pegada de carbono da dieta foi estimada com base nos dados de dois registros alimentares de 24 horas, obtidos em 2008 e 2009, de uma amostra probabilística da população brasileira com 10 ou mais anos de idade (n = 34.003) e em coeficientes de impacto ambiental de alimentos e preparações culinárias consumidos no Brasil (gCO2e/kg). Médias com intervalos de confiança de 95% do consumo alimentar (kcal/pessoa/dia) e da pegada de carbono da dieta (gCO2e/pessoa/dia e em gCO2e/2.000kcal) foram calculadas para o conjunto da população e para estratos segundo sexo, idade, renda, escolaridade, macrorregiões e Unidade Federativa. Modelos de regressão linear foram utilizados para identificar diferenças significativas (p < 0,05) na pegada de carbono da dieta de diferentes estratos sociodemográficos. RESULTADOS: A pegada média de carbono da dieta brasileira foi de 4.489gCO2e/pessoa/dia. Foi maior para o sexo masculino, para a faixa etária de 20 a 49 anos e para as regiões Norte e Centro-Oeste, e tendeu a aumentar com a renda e a escolaridade. O padrão de associação da pegada a variáveis sociodemográficas não se alterou substancialmente com o ajuste para diferenças na quantidade consumida de alimentos, exceto por uma redução no excesso relativo da pegada entre homens e pelo aumento no excesso relativo da pegada na região Centro-Oeste. CONCLUSÃO: A pegada de carbono da dieta brasileira excede em cerca de 30% a pegada da dieta humana que poderia atender, simultaneamente, os requisitos nutricionais de uma dieta saudável e a meta global de contenção do aumento da temperatura média do planeta. O padrão de associação dessa pegada às variáveis sociodemográficas pode auxiliar na identificação de alvos prioritários para ações públicas que visem a reduzir os impactos ambientais do consumo alimentar no Brasil.

RESUMEN

ABSTRACT OBJECTIVE To describe the Nova score for the consumption of ultra-processed foods (UPF) and evaluate its potential in reflecting the dietary share of UPF in Brazil. METHODS This study was conducted in São Paulo with a convenience sample of 300 adults. Using a tablet, participants answered a 3-minute electronic self-report questionnaire on the consumption of 23 subgroups of UPF commonly consumed in Brazil, regarding the day prior the survey. Each participant score corresponded to the number of subgroups reported. The dietary share of UPF on the day prior to the survey, expressed as a percentage of total energy intake, was calculated based on data collected on a 30-minute complete 24-hour dietary recall administered by trained nutritionists. The association between the score and the dietary share of UPF was evaluated using linear regression models. The Pabak index was used to assess the agreement in participants' classification according to the fifths of Nova score and the fifths of dietary share of UPF. RESULTS The average dietary share of UPF increased linearly and significantly with the increase of the Nova score for the consumption of ultra-processed foods. We found a substantial agreement in participants' classification according to the fifths of the distribution of scores and the fifths of the dietary share of UPF (Pabak index = 0.67). Age was inversely associated with a relatively high frequency of UPF consumption (upper fifth of the distribution) for both score and dietary share of UPF. CONCLUSION The Nova score for the consumption of ultra-processed foods, obtained in a quick and practical manner, shows a good potential in reflecting the dietary share of UPF in Brazil.


RESUMO OBJETIVO Descrever o escore Nova de consumo de alimentos ultraprocessados e avaliar seu potencial para refletir, no contexto brasileiro, a participação desses alimentos na dieta. MÉTODOS Estudo realizado na cidade de São Paulo com amostra de conveniência de 300 adultos, que responderam, em cerca de três minutos, em um tablet, a um questionário eletrônico de autorrelato sobre o consumo, no dia anterior, de 23 subgrupos de alimentos ultraprocessados comumente consumidos no Brasil. O escore de cada participante correspondeu ao número de subgrupos reportados. A participação de alimentos ultraprocessados no consumo alimentar do mesmo dia, expressa como percentual da ingestão total de energia, foi calculada por meio das respostas dos participantes a recordatório alimentar completo de 24 horas aplicado em cerca de 30 minutos por nutricionistas treinados. A associação entre o escore e a participação de ultraprocessados na dieta foi estudada por modelos de regressão linear. A concordância na classificação dos participantes segundo quintos do escore e quintos da participação de alimentos ultraprocessados na dieta foi avaliada pelo índice Pabak. RESULTADOS O percentual médio de participação de alimentos ultraprocessados na dieta aumentou linear e significativamente com o aumento do escore Nova de consumo de alimentos ultraprocessados. Observou-se concordância substancial na classificação dos participantes segundo quintos da distribuição do escore e quintos da distribuição do percentual de participação de alimentos ultraprocessados na dieta (índice Pabak = 0,67). Relação inversa da idade com a frequência de consumo relativamente elevado de alimentos ultraprocessados (quinto superior da distribuição) foi observada tanto para o escore quanto para a participação de alimentos ultraprocessados na dieta. CONCLUSÃO O escore Nova de consumo de alimentos ultraprocessados, obtido de forma rápida e prática, apresenta bom potencial para refletir, no contexto brasileiro, a participação desses alimentos na dieta.

RESUMEN

Based on previous studies, it has been found that goji berry (GB), popularly known as a 'miracle fruit', has excellent antioxidant potential and can be used in the treatment of skin disorders associated with ageing. This study aimed to incorporate GB into a structured cosmetic in order to optimise its penetration. Stability studies of the formulation, determination of the antioxidant activity of the extract and of the formulation, rheological measurements, SAXS, polarised light microscopy and bioadhesion analyses were performed. The results indicated the antioxidant activity of the extract, which can be incorporated into an emulsified cosmetic formulation. The emulsified formulation containing the extract remained stable, even after being submitted to thermal and luminous stresses for 30 days. In addition, rheological tests revealed that the addition of the GB soft extract reduced the viscosity of the formulation, increasing thixotropy and deformation. These systems were characterised by SAXS as a lamellar phase, which was confirmed by polarised light microscopy. These highly organised structures indicate their excellent stability. In vitro bioadhesion experiments revealed that these formulations exhibited skin adhesion strength statistically similar to commercial anti-ageing formulation. These results suggest that this formulation has excellent potential to be used as a topical treatment for ageing.

RESUMEN

ABSTRACT Objective We aimed to establish equations for dimensioning of the physical area and determining the required number of food handlers in food services of schools and to compare them with reference equations. Methods It was visited 44 municipalities located in the states of São Paulo (n=36) and Rio de Janeiro (n=8) between 2013 and 2014. The physical area for school food services was evaluated using a measuring tape. For all food services, we calculated the Maximum Attendance Capacity, which is the sum of small and large meals served during the busiest shift. A validated checklist was used to evaluate food safety practices. Linear regression models were developed to establish the proposed equations. Results In total, we evaluated 205 school units. Based on the data, the following equations were established: Equation A: area of production=15.22+(maximum attendance capacity×0.02), which estimates the minimum area needed for a school food service; and Equation B: the number of food handlers=2.17+(maximum attendance capacity×0.002), to determine the minimum number of food handlers needed. These equations were established based on school food services that presented adequate food safety practices (i.e., low health risk). Conclusion It was established new equations for calculating the size of the physical area for school food services and the required number of food handlers. These new equations can be used as a starting point in management planning of a school food service.


RESUMO Objective Estabelecer equações para o dimensionamento da área física e do número de manipuladores em serviços de alimentação escolar comparando-as com equações de referência. Métodos Foram visitados, entre 2013 e 2014, 44 municípios localizados nos estados de São Paulo (n=36) e Rio de Janeiro (n=8). A área útil dos serviços de alimentação escolar foi avaliada por meio de uma trena. Para todas as unidades foi calculada a Capacidade Máxima de Atendimento que é a soma das pequenas e grandes refeições servidas no turno de maior movimento. Para a avaliação das boas práticas de manipulação de alimentos foi utilizada uma lista de verificação validada. As equações foram estabelecidas por meio de regressão linear com base em serviços de alimentação escolar que apresentaram boa adequação das boas práticas (i.e. baixo risco sanitário). Resultados Foram avaliados 205 serviços de alimentação escolar. Com base nos dados foi determinada a Equação A: m2 da área de produção=15,22+(Capacidade máxima de atendimento×0,02) que estima a área mínima para um serviço de alimentação escolar e a Equação B: número de manipuladores=2,17+(Capacidade máxima de atendimento×0,002) para o número mínimo de manipuladores de alimentos. Conclusão Novas equações para cálculo do dimensionamento da área física de serviços de alimentação escolar e para o número de manipuladores de alimentos necessários foram estabelecidas. Essas novas equações podem ser utilizadas como ponto de partida para o planejamento gerencial de um serviço de alimentação escolar.

RESUMEN

Objectives: To describe the age group, clinical stage at diagnosis, treatment, and survival rates of breast cancer patients treated in a Brazilian specialized Cancer Center. Method: A hospital-based retrospective cohort study is presented herein, on women with breast cancer diagnosed between January 1, 2000 and December 31, 2012. Data were extracted from the Hospital Cancer Registry of the A.C.Camargo Cancer Center. Data on age group, histology of the tumor, TNM classification, clinical stage and treatments were described in absolute and relative frequencies for three periods. Survival curves were estimated with the Kaplan-Meier estimator. Hazard ratio (HR) and 95% confidence interval (95%CI) were calculated for all variables. Results: A total of 5,095 female breast cancer patients were identified, with most stages classified as I and II (60%). The overall survival was 82.7% for the period of 2000­2004, and 89.9% for 2010­2012 (p<0.001). Patients with invasive ductal carcinoma, who were treated with surgery and hormonal therapy, showed a reduction in the risk of death in the most recent period HRadj=0.42 (95%CI 0.34­0.53) (2010­2012). Conclusions: Early stage diagnosis and combined treatment (including HT) are predictive prognostic factors for high survival rates in patients with invasive breast cancer. Specialized cancer centers can provide valuable indications regarding cancer control policies, evaluating overall survival for breast cancer and its associated prognosis.


Objetivos: Descrever as faixas etárias, estadiamento clínico ao diagnóstico, tratamento e sobrevida global das pacientes com câncer de mama tratadas em um centro de câncer brasileiro. Método: Estudo de uma coorte retrospectiva de base hospitalar, com mulheres diagnosticadas de câncer de mama entre 1º de janeiro de 2000 e 31 de dezembro de 2012. Os dados foram extraídos do Registro Hospitalar de Câncer do A. C. Camargo Cancer Center. Faixa etária, tipo histológico, classificação TNM, estadiamento clínico e tratamento foram descritos em frequência absoluta e relativa estratificados em três períodos. As curvas de sobrevida global foram estimadas pelo método de Kaplan-Meier. A Hazard ratio (HR) com intervalo de confiança de 95% foram calculados para todas as variáveis. Resultados: O total de 5.095 pacientes mulheres com câncer de mama foi identificado, a maioria era estágio inicial 60% (I e II). A sobrevida global foi de 82,7% para o período de 2000­2004 e 89,9% para 2010­2012 (p<0,001). Pacientes com carcinoma ductal invasivo que foram tratadas com cirurgia e hormonioterapia, mostraram redução do risco de morte no período mais recente HRaj=0,42 (0,34­0,53 em 2010­2012). Conclusões: Diagnóstico precoce e tratamento combinado (incluindo hormonioterapia) são fatores prognósticos preditivos para altas taxas de sobrevida em pacientes com câncer de mama invasivo. Centros especializados em câncer podem prover informações valiosas sobre as políticas de controle do câncer, avaliando a sobrevida global do câncer de mama e fatores associados ao prognóstico.
